## Step-by-Step Ruger Mark II Disassembly Guide
Now, let’s get into the actual disassembly process. Follow these steps carefully, referring to the images and diagrams provided (if any – this content is purely text-based for now). Remember, patience and attention to detail are key.
### 1. Field Stripping the Ruger Mark II
Field stripping is the basic level of disassembly required for routine cleaning and maintenance. It involves separating the major components of the firearm.
1. **Ensure the firearm is unloaded.** (Repeat this check!)
2. **Remove the Magazine:** Press the magazine release button and remove the magazine.
3. **Lock the Bolt Back:** Pull the bolt back and engage the bolt stop. This will hold the bolt in the open position.
4. **Remove the Mainspring Housing Latch:** Locate the mainspring housing latch at the rear of the grip frame. Pull it down and out.
5. **Remove the Mainspring Housing:** With the latch removed, the mainspring housing can now be pulled down and out of the grip frame. It might require a little wiggle.
6. **Separate the Upper Receiver:** With the mainspring housing removed, the upper receiver (the part containing the barrel and bolt) can now be separated from the grip frame. Slide it forward off the frame.
7. **Remove the Bolt:** With the upper receiver separated, you can now remove the bolt. Pull the bolt back and lift it out of the receiver.
### 2. Detailed Bolt Disassembly
The bolt is a critical component of the Ruger Mark II, and detailed disassembly is necessary for thorough cleaning and inspection. This step requires more care.
1. **Locate the Firing Pin Retaining Pin:** This small pin holds the firing pin in place. It’s usually located on the rear of the bolt.
2. **Using a Punch, Carefully Drive Out the Firing Pin Retaining Pin:** Support the bolt on a solid surface and use a punch to gently drive out the retaining pin. Be careful not to damage the bolt.
3. **Remove the Firing Pin:** Once the retaining pin is removed, the firing pin can be pushed out from the rear of the bolt.
4. **Remove the Extractor:** The extractor is located on the side of the bolt. Use a small tool or punch to carefully pry it out. Be aware that the extractor is spring-loaded, so it may eject forcefully.
5. **Remove the Extractor Plunger and Spring:** Once the extractor is removed, you can remove the extractor plunger and spring from the bolt. These are small parts, so be careful not to lose them.
### 3. Magazine Disassembly
Disassembling the magazine allows you to clean the interior and ensure proper feeding. This is a relatively simple process.
1. **Locate the Magazine Base Plate Retaining Button:** This button is usually located on the bottom of the magazine.
2. **Press the Retaining Button:** Use a punch or small tool to press the retaining button.
3. **Slide the Base Plate Off:** While pressing the retaining button, slide the base plate off the magazine. Be careful, as the spring is under tension.
4. **Remove the Spring and Follower:** Once the base plate is removed, you can remove the spring and follower from the magazine body.
### 4. Cleaning and Inspection
With the Ruger Mark II disassembled, you can now clean and inspect the individual parts. Use gun cleaning solvent, brushes, and patches to remove dirt, grime, and powder residue.
* **Barrel Cleaning:** Use a cleaning rod and bore brush to clean the barrel. Follow up with patches until they come out clean.
* **Bolt Cleaning:** Clean the bolt thoroughly, paying attention to the firing pin channel and extractor area.
* **Frame Cleaning:** Clean the grip frame and upper receiver with a brush and solvent.
* **Magazine Cleaning:** Clean the magazine body, spring, and follower with solvent.
Inspect all parts for wear, damage, or cracks. Replace any worn or damaged parts as needed. Pay close attention to the firing pin, extractor, and springs. These are common wear items.
### 5. Reassembly: Putting It All Back Together
Reassembly is the reverse of disassembly. Follow these steps carefully, ensuring all parts are properly aligned and seated.
1. **Reassemble the Magazine:**
* Insert the spring and follower into the magazine body.
* Slide the base plate back onto the magazine, ensuring the retaining button clicks into place.
2. **Reassemble the Bolt:**
* Insert the extractor plunger and spring into the bolt.
* Install the extractor, ensuring it is properly seated.
* Insert the firing pin into the bolt.
* Reinstall the firing pin retaining pin, ensuring it is flush with the bolt surface.
3. **Reassemble the Upper Receiver:**
* Slide the bolt back into the upper receiver.
4. **Reassemble the Pistol:**
* Slide the upper receiver onto the grip frame.
* Reinstall the mainspring housing, ensuring it is properly seated.
* Reinstall the mainspring housing latch.
### 6. Function Check
After reassembly, it’s essential to perform a function check to ensure the firearm is operating correctly. This involves:
* **Checking the Safety:** Ensure the safety lever engages and disengages properly.
* **Checking the Trigger:** Ensure the trigger pulls smoothly and resets correctly.
* **Checking the Bolt:** Ensure the bolt cycles smoothly and locks back on an empty magazine.
**Important:** *Never load live ammunition during a function check. Use dummy rounds or snap caps.* If you encounter any issues during the function check, disassemble the firearm and recheck your work. If you are still unable to resolve the issue, consult a qualified gunsmith.
## Advanced Troubleshooting: Common Issues and Solutions
Even with careful disassembly and reassembly, you may encounter some common issues. Here are some troubleshooting tips:
* **Failure to Eject:** This can be caused by a dirty extractor, a worn extractor spring, or a dirty chamber. Clean the extractor and chamber thoroughly. Replace the extractor spring if it is weak.
* **Failure to Feed:** This can be caused by a dirty magazine, a weak magazine spring, or a dirty feed ramp. Clean the magazine and feed ramp. Replace the magazine spring if it is weak.
* **Light Strikes:** This can be caused by a dirty firing pin channel, a worn firing pin, or a weak hammer spring. Clean the firing pin channel thoroughly. Replace the firing pin or hammer spring if they are worn.
If you are unable to resolve these issues yourself, consult a qualified gunsmith.
